Overview

The sanitary rotary lobe pumps of the NOVAlobe range provide reliable, efficient and hygienic operation even under the most demanding conditions. The pumps are specially designed for viscous media and for applications where gentle pumping or dosing is required. They are made from high quality materials to meet the world’s strictest hygiene standards, e.g. EHEDG, QHD and GOST. The pumps are CIP- and SIP-capable and meet the GMP requirements regarding FDA-approved materials.

The robust construction keeps the pumps running even under high-volume operating conditions and with difficult media. To permit fast service and maintenance, the pumps are designed for easy access and for the quick removal and replacement of parts.
